The current research offers a new theoretical perspective on the relationship between power and persuasion. An agentic-communal model of power is presented that proposes power affects both the type of messages generated by communicators and the types of messages that persuade audiences. Compared to low-power and neutral states, high-power states produce a greater emphasis on information that conveys competence. As a consequence, high-power communicators generate messages with greater competence information and high-power audiences are persuaded more by competence information. In contrast to high-power states, low-power states produce a greater emphasis on information that conveys warmth. As a result, low-power communicators generate messages with greater warmth information, and low-power audiences are persuaded more by warmth information. As a result of these two outcomes, a power matching-effect occurs between communicator and audience power: high-power communicators are more effective in persuading high-power audience members, whereas low-power communicators are more effective in persuading low-power audience members. Four experiments find support for these effects in oral and written contexts with three distinct manipulations of power. Overall, these experiments demonstrate that the success of a persuasive communication can be affected by the alignment between the psychological sense of power of the communicator and the audience.
